Abstract:

Objectives: We reviewed our experience of Bilateral Pulmonary Artery Banding (BPAB) in neonate
and assessed the predictors of postoperative mortality.
Methods: From May 2007 to December 2017, a total of 21 consecutive patients who underwent
staged surgical treatment using BPAB strategy for univentricular repair of the complex congenital
heart disease in neonate. We reviewed patients’ clinical perioperative data, such as surgical
outcomes, body weight gain, and the Interval Period (IP) between BPAB and Norwood operation.
We performed BPAB operation at mean 6.8 ± 4.7 days after birth. The mean weight was 2.8 ± 0.4
kg at the time of BPAB.
Results: All patient underwent the Norwood operation included Glenn operation (n=6) or
atrioventricular valve repair (n=2). Eighteen patients reached the total cavopulmonary connection.
There were three early death and accounting for a hospital mortality of 14.3%. Mortality was strongly
associated with the interval period between BPAB and second-stage operation, mortality was high
(25%) with the IP<90 days, and low (7.7%) with the IP between BPAB and Norwood operation >90
days (p<0.03).
Conclusions: Long interval period between BPAB and Norwood operation seem to be associated
with better surgical results.
